Unlock/Ungroup Commands Cause Constant Hanging/Odd Cursor Behavior in MacOS

This issue was noted by other users in 2024, but started happening to me a few months ago and I've yet to find a solution.  In most cases when I execute an Ungroup or Unlock command, Illustrator hangs for 5-10 seconds. Often, the cursor also becomes "possessed", eeirly sliding across the screen and not responding to commands.  Then, once the hiccup has passed, back to normal as if nothing has happened.  Needlessy to say this is a severe drag on my workflow and I am getting asked why things are taking so long to complete.  (Unfortunately, the answer is because Adobe...)

It is doubtful that it's a hardware or settings issue, as Illustrator worked flawlessly when I first got this machine and the bug can be triggered no matter how simple the file is -- even just ungrouping a few open paths on an empty artboard will do it.  I have also completely wiped and reinstalled both the OS and all software, so it's not a virus or other issue.  My suspicion is that the problem lies either within Adobe's software or MacOS itself.  But there has been a full version update of AI since it begain, which unfortunately did not resolve the issue, so I'm begenning to feel like affected users are simply stuck with AI working at 80% efficiency indefiniately.
